Mechanism of Stimulation of Myogenesis under the Action of Succinic Acid through the Succinate Receptor SUCNR1.

Effect of succinic acid on the processes of myogenesis was investigated in the study with the cells of C2C12 line. In the concentration range 10-1000 µM, succinic acid stimulated the process of myogenic differentiation, increasing the levels of myogenesis factors MyoD (at all stages of myogenesis) and myogenin (at the stage of terminal differentiation). Presence of the succinate receptors SUCNR1 was revealed in the C2C12 cells using Western blotting, level of which decreased during myogenesis.

Development and validation of a methodology for quantitative determination of malondialdehyde by HPLC-MC/MS.

A bioanalytical technique for quantitative determination of MDA by HPLC-MS/MS. The proposed method for determining MDA includes the release stage of bound MDA and excludes the derivatization reaction. The lower limit of quantitative detection was 600 nmol/l, the volume of the required sample was 10 µl, the analysis time was 7 min.
